It was actually flat silver/volt! i've now got all the volt-infused bands (black/volt that came on my s2, silver/volt, midnight fog and desert sand/volt)... and I just discovered that if i set the numerals duo face to volt I don't have to have top and bottom looking the same after all, there's an option for the hour to be filled in and the minutes to be an outline. so i now switched that one to volt too. the only face i have that's not volt is infograph, because it looks - quite frankly - crap in anything other than multicolour.
I'd be tempted to pick up either pure platinum/white or flat silver/white (the same seller has them) if I used the plain aluminium watch day to day, but my S4 is my sleep watch and my S5 is a space grey... i'm probably skipping the series 6 so... i... probably... don't... ne.. ne... ne... nee... need them. i don't. i don't...
but in all seriousness, that colour pairing is covered well enough by the summit white sport loop that i probably don't need it.
